How do electricians find power leakages and where the problem is without breaking the wall? (I have one working on my house rn and he found the leakage with the power out)

Electricity doesn’t “leak”. Electricity travels in a circuit, meaning it has to have a path to return to where it’s coming from. If there is a “short circuit” it means that the electricity found another way to “return” from its source. This can cause electrical problems, or even a fire.
Electricity also has to have a solid, unbroken path from its source to the place it is to be used. This is called continuity. An electrician has tools that can test for continuity, or an unbroken path, through an electrical circuit, using independent electrical signals they send out and receive from their own tools.
